Why a "fast" connection can still fail an exam

Most students prepare for an online exam the same way they prepare for a movie night: they run a speed test, see a big download number, and assume they are fine. A proctored exam is nothing like a movie night. Streaming video is forgiving - your player buffers several seconds ahead, so a brief hiccup goes unnoticed. A proctored exam is a live, two-way session: your webcam streams your face to the proctor the entire time, the lockdown browser sends constant "heartbeat" signals to prove you are still there, and every click is recorded in real time. Nothing is buffered, so nothing forgives a spike.

This is why a 500 Mbps connection with spiky ping can be worse for an exam than a stable 20 Mbps line. What matters is not how much data can rush through at peak, but whether the connection holds steady minute after minute. Dropouts of even a few seconds can freeze your webcam feed, break the proctoring session, or lock you out of the exam entirely. When you test your connection before exam day, test for stability - steady ping, steady upload, and near-zero packet loss - not just a headline download speed.

The four checks and why proctoring software is picky

The checker above scores your connection on four checks, each with a threshold chosen for what proctoring platforms actually need.

Download speed of at least 5 Mbps. The exam itself downloads very little - questions, images, the occasional video prompt. Five megabits per second leaves plenty of headroom for the proctoring software's background traffic.

Upload speed of at least 3 Mbps. This is the one most people overlook. Your webcam feed goes upstream for the entire exam, often at 720p or better, and it shares that upstream bandwidth with the lockdown browser's monitoring data. Anything under 3 Mbps risks a frozen or dropped video feed - which is exactly what gets exams flagged.

Ping of 150 ms or less. Ping is the round-trip time for a packet. The lockdown browser and proctoring server exchange frequent small messages; high ping turns those into laggy, out-of-sync exchanges and can trigger "connection lost" warnings even while your speed test looks fine.

Packet loss of 2% or less. Packet loss means data that never arrives and has to be resent. A little loss is normal, but above 2% your webcam feed stutters, audio breaks up, and the proctoring heartbeat can fail - the most common cause of mysterious mid-exam disconnects on otherwise "fast" connections.

Worked example

Say your speed test shows 50 Mbps download, 10 Mbps upload, 40 ms ping, and 0.5% packet loss, and your exam runs 3 hours. Enter those numbers, set the backup connection to "Yes", and hit Check. The result reads: "Checks passed: 4 / 4 (download ok, upload ok, ping ok, packet loss ok)." followed by "Your 3.0-hour exam needs a stable line the whole time." The verdict is "Exam-ready - your connection clears all four checks." plus the reassurance: "Good - you have a backup connection if the main one drops." Every threshold is comfortably cleared: 50 is well above the 5 Mbps download minimum, 10 above the 3 Mbps upload minimum, 40 ms is far under the 150 ms ping ceiling, and 0.5% loss is a quarter of the 2% limit.

Tips to make your connection exam-proof

First, use a wired Ethernet cable instead of Wi-Fi if you possibly can. Wi-Fi adds jitter and is vulnerable to interference from neighbors' routers, microwaves, and even a family member walking between you and the router. A cable removes all of that at once.

Second, restart your router on the morning of the exam. It clears stale sessions and memory leaks that accumulate over weeks of uptime, and it often takes less than two minutes.

Third, shut down everything that competes for bandwidth: cloud backup and sync apps, automatic OS updates, streaming boxes, and other devices on the same network. Ask others in the house to avoid video calls during your exam window.

Fourth, keep a phone hotspot configured and tested as a ready-to-switch backup. Run this checker on the hotspot beforehand so you know it passes, keep the phone plugged into power, and know exactly how to switch networks in under a minute.

Finally, run the checker on the exact setup you will use on exam day - same room, same device, same network. A test run from your desk means far more than one from the living-room couch.
